Copper (miniature)
Rubtsovskoe mine, Rudnyi Altai, Altaiskii Krai, Russia
The thick branches on this wonderful copper crystal from Russia jut out in every direction. You can only really appreciate it in a movie. Starting from a small base, it seems to reach out in every direction just like a tree spreading its branches for light. I guess that's why this kind of crystal growth is called dendritic growth! 3.5 x 2.0 x 2.5 cm and perfect.
